I get java.lang.NullPointerException while using driver.get

Question

I am trying to automate search functionality on a website. While running the test case, Firefox browser is opened and the website is rendered correctly but still system shows null pointer on line where i call driver.get(URL); The code snippet is as follows:

    package testcases;


    import java.util.concurrent.TimeUnit;
    import org.junit.*;
    import static org.junit.Assert.*;
    import org.openqa.selenium.*;
    import org.openqa.selenium.firefox.FirefoxDriver;

    public class SaavnSearchWeb {
      private WebDriver driver;
      private String baseUrl;
      private boolean acceptNextAlert = true;
      private StringBuffer verificationErrors = new StringBuffer();

      @Before
      public void setUp() throws Exception {
        driver = new FirefoxDriver();
        baseUrl = "http://saavn.com";
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
      }

      @Test
      public void testSaavnSearchWeb() throws Exception {

        driver.get(baseUrl + "/s/artist/deepika-padukone-album/36LfdYhYGvc_");
        if (isElementPresent(By.id("q"))){
            driver.findElement(By.id("q")).sendKeys("cocktail");
            driver.findElement(By.linkText("Tum Hi Ho Bandhu")).click();
        }
      }

      @After
      public void tearDown() throws Exception {
        driver.quit();
        String verificationErrorString = verificationErrors.toString();
        if (!"".equals(verificationErrorString)) {
          fail(verificationErrorString);
        }
      }

      private boolean isElementPresent(By by) {
        try {
          driver.findElement(by);
          return true;
        } catch (NoSuchElementException e) {
          return false;
        }
      }

      private boolean isAlertPresent() {
        try {
          driver.switchTo().alert();
          return true;
        } catch (NoAlertPresentException e) {
          return false;
        }
      }

      private String closeAlertAndGetItsText() {
        try {
          Alert alert = driver.switchTo().alert();
          String alertText = alert.getText();
          if (acceptNextAlert) {
            alert.accept();
          } else {
            alert.dismiss();
          }
          return alertText;
        } finally {
          acceptNextAlert = true;
        }
      }
    }

The stack trace is as follow:

Can someone please help me with this?

post the class completely if possible .. want to know how driver is declared — StrikerVillain, Oct 14 '15 at 20:16
`public class SaavnSearchWeb { private WebDriver driver; private String baseUrl; 'before' public void setUp() throws Exception { driver = new FirefoxDriver (); baseUrl = "http://www.saavn.com"; driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS); } 'test' public void testSaavnSearchWeb() throws Exception { driver.get(baseUrl + "/s/artist/deepika-padukone-album/36LfdYhYGvc_"); if (isElementPresent(By.id("q"))){ driver.findElement(By.id("q")).sendKeys("cocktail"); driver.findElement(By.linkText("Tum Hi Ho Bandhu")).click(); } }` — user5446733, Oct 14 '15 at 20:31
tried your code.. No error for me. The test case passed successfully. Which version of Selenium and JUnit are you using. Also, you are running this as JUnit, right? — StrikerVillain, Oct 14 '15 at 21:53
Agreed. Code works fine. Not sure if `By.id("q")` is a valid locator here. — AGill, Oct 14 '15 at 21:58

You are not using the right protocol for the url. Change the baseUrl to as follows:

baseUrl = "http://saavn.com";

And run the code.

@A Gill- tried with this but same error. When i run the testcse, url is invoked correctly once but control does not go to the next line and after some time. i get null pointer exception again at the same line for driver.get(URL), but the invoked browser is still open – user5446733 Oct 14 '15 at 21:06
Try this.`public class SaavnSearchWeb { private WebDriver driver; private String baseUrl; @Before public void setUp() throws Exception { driver = new FirefoxDriver (); baseUrl = "http://www.saavn.com"; driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS); } @Test public void testSaavnSearchWeb() throws Exception { driver.get(baseUrl + "/s/artist/deepika-padukone-album/36LfdYhYGvc_"); }` – AGill Oct 14 '15 at 21:09
@A Gill: control does not move ahead to the next line in after this line of my code – user5446733 Oct 14 '15 at 21:11
Can you please post your full code and the error stack to the original question. I am sure someone will be able to solve your problem. – AGill Oct 14 '15 at 21:15
So you are saying, the `driver.findElement();` line is not getting executed but the you are able to go the defined url? – AGill Oct 14 '15 at 21:53
@A Gill: thats the isssue I am facing – user5446733 Oct 15 '15 at 05:44
Ok, so thats a different question now. You original question says you are getting java.lang.NullPointerException while you are trying to execute `driver.get()` but that problem seems to be resolved. Please update the question with what you want to accomplish (whats the use case) or please ask a new one. – AGill Oct 15 '15 at 17:45
